<br><font size=2 face="sans-serif">Much more detail is needed for your answers. There are many systems and mods thereof. You need the exact type of color and clearcoat system, what catalyst you have, what clear you have and what basecoat you have.</font>
<br><font size=2 face="sans-serif">In general for basecoats such as DBU an others you can mask in 40 minutes. Doubt it for clearcoat, even with the fast catalyst, and all of this is temperature dependent.</font>
<br><font size=2 face="sans-serif">The amount of reducer reccomendend on the can is not necessarily the best for our applications. It is the smallest amount that allows a car paint-guy to apply to a car, which is not exaclty weight sensitive, and meet EPA VOC regs...thinner smoother coats can be achieved by adding more reducer, but I must caution....you are killing us all and creating more greenhouse effect.....so you must then live with that guilt. Next time you see a perfect paint job....know that the person is not and environmentalist!</font>

<br>
<br>
<br><font size=2 face="Courier New">I am going to pain a Temptation this weekend and bought the ppg clearcaot <br>
base cat system. I was reading the paper that came with the paint and it says <br>
that we can mask in 20-40 minutes between coats. Is that correct? Can you pain <br>
and mask multiple colors in one day?<br>
<br>
Do you really have to clearcoat within 24 hours or is there some wiggle room?<br>
<br>
Do most people mix the paint reducer 1:1 as they suggest or do they reduce <br>
further?<br>
<br>
Does the paint build up a film thickness excessively or is it thin? I was <br>
thinking how Concept build a thick heavy film if one is not careful.<br>
<br>
Thanks,<br>
